JQuery username validation - Ajax call

I am currently using JQuery's validation plugin for basic form validation such as required fields.

I want to add functionality so that when the user types in the username field, an ajax call is triggered to check whether the username is already taken. My requirements are:

  • Preferably integrate with JQuery Validation plugin, rather than writing a custom function
  • I want the lookup to occur on the keyup event
  • I want the lookup to be triggered approx开发者_Go百科 0.5 seconds after the keyup event has occurred.

Thanks!
